Abstract
The invention relates to a seamless hot-finished steel tube (16), whereby a thick-walled hollow block (8) is formed from a block (1) heated to the molding temperature in a first molding process by means of stamping, which is then drawn at the same temperature in a second molding step, by rolling with a change in diameter and wall thickness to give the pre-tube (bloom) and a finished tube is produced wherefrom in a third molding step by reduction rolling, characterized in that the second and third molding steps defined by rolling are replaced by one molding step in the form of a radial forging process, using an internal tool (11) inserted into the hollow block (8) and at least two forging cheeks of a forging machine (10), acting on the outer surface of the hollow block (8), whereby the hollow block (8) is alternately rotated and axially shifted during the idle stroke phase of the forging cheeks.
